China wholesale Thin Copper Foil - Tin Plated Copper Foil – CIVEN

Product Introduction

Copper products exposed in the air are prone to oxidation and the formation of basic copper carbonate, which has high resistance, poor electrical conductivity and high power transmission loss; after tin plating, copper products form tin dioxide films in the air due to the properties of tin metal itself to prevent further oxidation. Tin can also form a similar film in halogen, so that the copper products after plating have good corrosion resistance and weldability, and at the same time have a certain strength and hardness, so they are widely used in electrical and electronic industry products; because tin metal is non-toxic and tasteless, the products after plating are also widely used in the food industry. The tinned copper foil produced by CIVEN METAL has a good surface finish and uniform tin layer thickness. They can be annealed and slit according to customer requirements.
